OIL-GAS BURNER.

Specification of Letters latent.

Patented July 13,1920.

Application filed November 29. 1918. Serial No. 264,548.

To all whom may concern:

. l e it known that 1, JAMES C. TAYLOR, a citizen of the United States, and resident of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful improvements in Uittias Burners, of which the following is a specification.

This invention relates to combustion devices to be placed in a stove or like structure for the purpose of enablingthe stove to use gasified liquid fuel, and the object oi the invention is to improve the details of construction t such a burner and render the same more economical and ellective.

lVith these and other objects in View, the

invention consists of certain novel features of construction, as Will be more tully described, and particularly pointed out in the nmunted upon a stove grate, the rest of the stove not being shown.

Fig. 2 is a top view of the base member with the burner pipe and mixing chamber removed.

Fig. 3 is a detail in perspective showing the adjustable damper.

Fig. l is a top view showing the spirally corrugated walls of the cone-shaped mixing chamber.

F 5* is a detail showing a portion of the mixing chamber with one of its bendable ears projecting from its lower edge.

Referring to the drawings, designates the base oi? the burner, which is preferably "formed hollow and elongated so as to it into the lire box 0'1 a stove or the like and is designed more particularly to rest upon the grate 1]., as illustrated in Fig. 1. This base member is provided with a top plate 12 through which two sets of draft openings 1! are shown. one at each end thereof to accommodate the device when two burners are mounted on this plate.

Around the edge of this plate is formed a rim or flange let and a pair of bosses 15 are termed at either end of this plate inside of the flange the same being internally tapped to receive the threaded ends of the burner-pipe standards 16.

These burner pipes are preferably formed substantially in the shape of the letter P,

one portion of each pipe being bent around in loop 't'orm and its free end 1? turned back to project toward the standard portion 16.

This free end is plugged as at 18 and near this end is formed an upwardly. directed jet openlng l9.

By my improved construction and arrangement of burner pipes, I am enabled to bend a stock pipe of iron or brass into exactly the desired shape to form a complete burner pipe and that without producing joints or connections of any sort in the pipe, and by this construction it will be seen that I am enabled to screw the threaded end of each pipe into its threaded boss without having one burner pipe in any way interfere with the positioning of the other.

Beneath the jet' end of each pipe I have provided a shallow trough 20 which is filled with-asbestos wicking or the lil :e,so that the oil may be run over from the j et if desired, to drop upon this wick, which, when lighted, then serves as a torch to light the jet end to assist in converting the oil supply into a gas.

Over this lighting wick and about the openings 13 through the base plate, I have located a mixing chamber 21, the walls of which are preferably arranged in a conical shape. The lower edge of this cone is provided with a plurality of downwardly extending cars 22 which are adapted to project through the openings 23 in the base and when bent to one side they serve to securely lock this conical mixing chamber to the base.

In some instances it is found of advan tags to form the walls of this mixing chamher with spiral corrugations 36 so that as the air is drawn up through the openings 13 in the base these walls thus formed will impart to this column of air a spiral or whirling motion which will also act upon the rising et oi gas from the opening 19 thereby serving to break up the flow of both and cause this gas to mix more thoroughly with the oxygen of the air, to produce a more perfect combustlon and consequently a more intense heat with greater fuel economy.

In order to obtain a still greater eiiiciency from the flame I have also provided a spreader member 28 which is supported from the upper portion of the burner pipe by bands 29 and, I have corrugated or formed} teeth 30 about the edge of this spreader member so that the flame will be 7 broken up to permit the air to more readily mix therewith and so further intensify the heating efficiency of the burner.

The top of this spreader is preferably formed concave as at 31 for the purpose of receiving a supply of asbestos wicking which" may be lighted in starting the stove to assist in heating and gasifying the oil supply as it is passing around to the jet 19.

.In order to more perfectly control the air supply through the openings 18 I have provided a damper 2% which is centrally piv-' otedat 25 and is provided with an operating handle 26 extending up through the segmental opening 27 in the base.

As a matter of convenience I haveextended this heatingwick 20 out beyond the edge of the, mixing chamber so that it may be readily lighted from the outside without removing the cone. 7 v v The supply to the burners isled from a receptacle (not shownlthrough the pipe 32 which is connected to the branch pipes 33 which lead up through the grate 11- and short pipes 53% to the burner pipes 16. 7 These branch pipes are each'provided witha valve 35 so that either one or both of the burners may be lighted if desired. These branch pipes are preferably constructed of ductile or bendable material such as copper, brass or the-like whereby they may be bent to readily find their way through the stove grate and out throughthe, draft openings in the front of the stove by which construction myimproved heatermay be applied to any ordinary coal stove-or furnace without being obligated to drill or boreholes or other in presence of one wise disfigure the stove to which the device s app 1 have shown and described this burner as being double but a single burner pipe may be attached to a single base plate if desired,

' The foregoing description is directed solely toward the construction illustrated,

.but I desire it to be understood that I reserve the privilegeof resorting to .all the 'mechanical changesto'which the device is susceptible, the invention being defined and limited only bythe terms of the appended claims. to r I claim: a r 1.
